TL;DR: An interactive, regression-based, normative score online calculator was created to serve as an additional resource for UDS clinical researchers, especially in guiding interpretation of individual performances that appear to fall in borderline realms and may be of particular utility for operationalizing subtle cognitive impairment present according to the newly proposed criteria for Stage 3 preclinical Alzheimer's disease.

TL;DR: The ecological validity of four Delis-Kaplan Executive Function System tests was tested by examining how well performance on D-KEFS measures predicted observed daily functioning in community-dwelling older adults, and the only measure of executive functioning that accounted for unique, independent variance in observed functional ability.

TL;DR: Results suggest that change in cognitive activity from one's previous level has at least a transitory association with cognitive performance measured at the same point in time, and not supporting the concept that engaging in Cognitive activity at an earlier age increases one's ability to mitigate future age-related cognitive decline.

TL;DR: The factor structure of the ADNI Neuropsychological Battery across older adults with differing levels of clinical AD severity based on the Clinical Dementia Rating Scale resulted in five factors that were invariant across levels of cognitive impairment.

TL;DR: In this paper, the authors investigated the relationship between social activity and cognitive function over time using a coordinated data analysis approach across four longitudinal studies and found that changes in social activity were not consistently associated with cognitive functioning.
